Feature Description

Make an interface out of Drv/LinuxSpiDriver protocol. See #2255 for an example interface change set.

The following three ports should be pulled out of Drv::LinuxSpiDriver into Svc/Interfaces/SpiInterface.fppi such that other Spi implementations can use it.

Note: annotations should be added to explain what each port does.

Hello, I was wondering if there is documentation on what this port does. Im assuming it reads and writes?

[menaman123]

Would the description be like this: @ Port to perform synchronous read and write operations over the SPI bus

[LeStarch]

I would say "Port to perform a synchronous read/write operation over the SPI bus"...but you basically have it. The nuance I am trying to capture here is that SPI calls are both read and write at the same time.

Follow up question, do i need to add anything to the cmake file so that there wont be any sort of failures?
